Letters Patent No. $7,221, dated February 23, 1869.

IMPROVEMENT IN DAMPERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, L. O. TABER, of Eaton, in the county of Madison, andState of New York, have ina stove, or stove-pipe, a damper which willopen itself when there is more fire than is required, and which willclose itself when there is less fire than is required, admit-ting air tothe flue or pipe when open,'tliereby checking the draught through thefire, and when closed, causing the draught to pass through the fire.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my improved damper as follows, viz

I apply, to the back boiler-hole of .a'cook-stove, a rim, A.

'B is a cover supported upon its pins. One side of said cover is enoughheavierthan the other, to open it, as shown in the drawings, figs. 1 and2.

Under the heavy side of said cover, I apply the long arm of lever E, andto the short arm of said lever, I apply a brass rod,.F, partlyencircling the rim A. One end of said rod is secured permanently to rimA at G.

To the opposite end of rod F, I apply a nut, H, for the purpose oftightening-or loosening said rod, by means of which the damper or covermay be so .set,

or adjusted, as to admit any desired amount of air.-

When the action of the damper is not needed, it may be fastened by meansof the button 6.

By the foregoing description it will beseen that my improved damper isonly applicable to a stove back of the fire. v

The damper-lid will open by its own grayity when uncontrolled, but bythe united action of the lever and the brass rod, it is held closed, orpartially closed, as adjusted by the thumb-screw, except when said rodis expanded by heat.

In Figure 5 my improved damper is shown as applied to the boiler-hole ofa stove.

In Figure 6-it is applied to an opening, cut for the purpose, in thestove-pipe. It may in like manner he Witnesses L. I. WHITE, A. W. Monse.
